Annualised hours are a specific kind of work contract that calculates the payment of an employee based on a whole year of work, rather than weekly or monthly payments. These types of contracts are put into place under the arrangement that an employee will work a specific number of hours a year, which can differ from month to month or even week to week.
These annualised hours give the employer flexibility over the amount of work they require from an employee throughout the year.
In this article, we are going to explain what annualised hours are, the benefits for employers and how they work.

What are Annualised Hours?
Unlike zero-hour contracts, annualised hours provide greater flexibility of working hours than a standard work contract with an agreement of a minimum number of overall hours.
The employee has to work a certain number of hours over the year but they are able to keep some flexibility about when they can and can’t work. They are sometimes referred to as ‘core hours’ which the employee regularly works and the rest of the hours are more flexible, for example when when there’s extra demand at work over peak seasons etc.
Industries Where Annualised Hours Are Most Present:
- Health and social care
- Education
- Wholesale
- Retail
- Admin
- Manufacturing
What are the Benefits for Employers?
- Helps you to budget better
- Reduces the need for temporary employees.
- It’s more cost-effective than paying employees overtime
- Reduced absences
- Promotes better use of resources
- Improved efficiency, flexibility and productivity
What are the Disadvantages?
- Accurately calculating the estimated workloads and working times can be difficult, especially in advance
- Some workshifts are unsociable, such as over weekends or bank holidays – therefore they are difficult to cover
- You may end up paying the contracted employees for working hours that they may not end up working
- It can be hard to keep in touch with the employees over periods when they are not working
How to Calculate Annualised Hours
The most straightforward way to calculate annual hours is to take the employees yearly contracted hours and deduct any annual leave entitlements, amounting to 20 days and then deduct any UK bank holidays, which is a total of 8 days.
In addition to this, you will need to calculate the annualised hours for holiday entitlement. This is similar to those who follow a standard working model. The only difference is that your holidays are divided into hours and not days.

What Should an Annualised Hours Contract Include?
When starting an employee on this type of contract, it’s extremely important to have a new employment contract written out to cover the following topics:
- Start date and expected end date
- Notice period
- Work location
- Holiday pay and entitlement
- Job title and expected duties
- Details regarding leave types
- Terms of employment
- Any other additional policies
Creating a clear and indept employment contract will help you to avoid any legal issues as an employer.
